Problem with setting config with command

So there's my code:

Code:

                if (args[0].contains("a") || args[0].contains("b") || args[0].contains("c") || args[0].contains("d") || args[0].contains("e") || args[0].contains("f") || args[0].contains("g") || args[0].contains("h") || args[0].contains("i") || args[0].contains("j") || args[0].contains("k") || args[0].contains("l") || args[0].contains("m") || args[0].contains("n") || args[0].contains("o") || args[0].contains("p") || args[0].contains("q") || args[0].contains("r") || args[0].contains("s") || args[0].contains("t") || args[0].contains("u") || args[0].contains("v") || args[0].contains("w") || args[0].contains("x") || args[0].contains("y") || args[0].contains("z"))
                {
                    player.sendMessage(prefix + " " + "§cThis command doesn't exist");
                }
                else
                {
                getConfig().set("healamount", args[0]);
                saveConfig();
                reloadConfig();
                player.sendMessage(prefix + " " + "§aHeal amount has been set to §b" + args[0] + "§a!");
                }

It sets the "healamount" option in the config.
But it looks like this:

Code:

healamount: '5'

It doesn't work with this " ' "

 

First, that is a completely inefficient way to check your args. Keep in mind you can also use characters like !@$% and so on. I would do it like this:

Code:

int i = getConfig().getInt("healamount");
try {
  i = Integer.parseInt(args[0]);
} catch (NumberFormatException e) {
  sender.sendMessage("§c" + args[0] + "§4 is not a number.");
} finally {
  getConfig().set("healamount", i);
}

Second, I don't completely understand what you're trying to do, but if you don't want the single quotes/apostrophes, then set the config with an int like this one-liner (I recommend you use the one above):

Code:

getConfig().set("healamount", Integer.parseInt(args[0]));

Third, if you're trying to use the ' character in YAML (config language), then just make a note to use two apostrophes (it will return one when using get(); )

 

' ' indicates that it is a string. You probably want it to be an int (without ' ')

So instead of setting args[0] (a String) to the config, make it an int with Integer.parseInt(args[0]), (put this in a try-catch block if it's not an int)
And remove reloadConfig()

I just noticed that you check for every letter in args[0]. That can be simplified with regular expressions

Code:

if (args[0].matches(".*[a-z].*")) {

.* matches any character.
[a-z] matches a single character in the range between a and z (case sensitive). Use [a-zA-Z] if you don't want it to be case sensitive.

It works like this: string must have any character, then a letter [a-z] and then again any character. (any character can be nothing too, "a.-." will work, "..,.-" doesn't)

 

Thanks for helping, it works now
